Cement Conveying Bucket Elevator

What is Cement Conveying Bucket Elevator?

Cement Conveying Bucket Elevator is a mechanical equipment used for vertical or inclined conveying of powdered, granular or small pieces of materials. It is widely used in cement, building materials, chemical, metallurgical and other industries. It lifts materials from low to high through a bucket fixed on a chain or belt. It has the characteristics of high efficiency, stability and good sealing.

What are the types of Cement Conveying Bucket Elevator?

Type	TD/D belt bucket elevator	TH/HL chain bucket elevator	NE plate chain bucket elevator	TB type plate chain bucket elevator (old-fashioned, gradually replaced by NE type)	Z type bucket elevator (rotating bucket type)
Traction component	Tape (temperature resistant 60°C, steel rope tape can reach 80°C)	Forged chain (high temperature resistant 250°C)	Plate chain (wear-resistant and impact-resistant)	Plate chain (similar to NE type, but with lower efficiency	Used for "horizontal-vertical-horizontal" transportation, such as cement packaging line; the transportation capacity can reach 100m³/h, and the lifting height is ≤100m
Applicable materials	Powdered and small granular cement, bulk density <1.5t/m³, low abrasiveness.	Cement clinker, slag, etc. with high abrasiveness	Powdered, granular cement and raw materials with moderate abrasiveness	Block clinker, slag, etc.
Features	Using centrifugal or mixed unloading, stable operation, low noise; conveying capacity can reach 500m³/h, lifting height ≤40m268; suitable for conveying raw materials and finished cement in cement plants.	Using gravity or mixed unloading, suitable for materials with high specific gravity; conveying capacity can reach 365m³/h, lifting height ≤50m; sturdy structure, suitable for high-temperature materials (such as rotary kiln clinker).	Using gravity-induced unloading, the conveying capacity is large (15~800m³/h); the lifting height can reach 50m, which is suitable for large-scale cement production lines; compared with the chain type, it runs more smoothly and has low maintenance costs.	Suitable for low-speed and heavy-load conditions, but has been replaced by the NE series

5. Easy maintenance: simple structure, easy maintenance and repair.

6. Strong adaptability: capable of conveying a variety of materials, including powder, granular and small pieces.

How does Cement Conveying Bucket Elevator work?

1. Loading: The material enters from the bottom feed port, and through the continuous movement of the hopper, the material is scooped up and loaded into the hopper.

2. Lifting: The hopper rises vertically or obliquely along the track of the elevator with the movement of the chain or belt.

3. Unloading: When the hopper reaches the top, the material is discharged from the hopper by gravity or centrifugal force and enters the discharge port.

4. Cycle: The empty hopper continues to move downward and returns to the bottom for the next loading, forming a continuous working cycle.

How to select a cement conveying bucket elevator?

Selecting the right bucket elevator for cement conveying requires careful consideration of cement properties, lifting height, capacity, power system, and other factors. Below is a detailed analysis for optimal selection.

1. Cement Characteristics (Material Properties)

Cement properties significantly impact elevator choice:

Parameter	Impact on Selection	Recommended Elevator Type
Powder (e.g., Portland cement)	Low abrasiveness, easy to convey	TD/D-type (belt-driven)
Granular (e.g., clinker, slag)	High abrasiveness, heavy	TH/HL-type (chain-driven)
Moisture content	Risk of clogging, sticking	NE-type (sealed design, anti-clogging)
Temperature	Hot clinker (>150°C)	High-temp chain (TH-type, heat-resistant)
Explosive dust risk	Need for explosion-proof motors	ATEX-certified models

2. Lifting Height (Vertical Conveying Distance)

The required lifting height determines structural strength and drive power:

Lifting Height (H)	Suitable Elevator Type	Notes
< 20m	TD/D-type (belt)	Economical, low maintenance
20m – 40m	NE-type (chain)	High stability, medium load
> 40m	TH/HL-type (heavy-duty chain)	Reinforced structure for long-distance lifting
Horizontal + Vertical (Z-type needed)	Z-type (chain-driven)	For complex layouts (e.g., packing plant)

3. Capacity (Tons/Hour or m³/Hour)

The required throughput affects bucket size, speed, and motor power:

Capacity (Q)	Bucket Size & Speed	Motor Power (kW) Example
< 50 m³/h	Small buckets, low speed (~1 m/s)	5.5 – 11 kW
50 – 200 m³/h	Medium buckets, moderate speed (~1.5 m/s)	15 – 30 kW
> 200 m³/h	Large buckets, high speed (~2 m/s)	37 – 75 kW (heavy-duty)

Formula for Power Estimation:

P=Q×H×ρ×g3600×ηP=3600×ηQ×H×ρ×g​

QQ: Capacity (t/h)

HH: Lifting height (m)

ρρ: Bulk density (~1.5 t/m³ for cement)

ηη: Efficiency (~0.8 for belt, ~0.7 for chain)

4. Drive System (Motor & Transmission)

The power system must match load and duty cycle:

Drive Type	Advantages	Best For
Gearmotor (Direct Drive)	Compact, efficient	Small/medium elevators (TD/NE-type)
Chain + Sprocket (Heavy-Duty)	High torque, durable	Large TH/HL-type for clinker
Variable Frequency Drive (VFD)	Speed control, energy-saving	Precise flow adjustment needed
Explosion-Proof Motor	Safe in dusty environments	Cement silo filling

5. Additional Selection Factors

Dust Control: Sealed elevators (NE-type) reduce pollution.

Maintenance Access: Removable panels for easy cleaning.

Material of Construction:

Stainless steel for corrosive environments.

Wear-resistant steel for abrasive clinker.

Summary: Cement Bucket Elevator Selection Table

Criteria	TD/D-type (Belt)	NE-type (Chain)	TH/HL-type (Heavy Chain)
Best for	Powder cement	General-purpose	Hot/clinker/slag

Final Recommendation

For fine cement powder: TD/D-type (low cost, low maintenance).

For mixed/hot materials: NE-type (balanced performance).

For high-temperature clinker: TH/HL-type (heavy-duty).
